Detailed Description

The present disclosure will now be described with reference to several example embodiments. It should be understood that these examples are described only for the purpose of enabling those skilled in the art to better understand and thereby enable the present disclosure, and are not intended to set forth any limitations on the scope of the technical solutions of the present disclosure.

As used herein, the term "include" and its variants are to be read as open-ended terms meaning "including, but not limited to. The term "based on" will be read as "based at least in part on". The terms "one embodiment" and "an embodiment" should be understood as "at least one embodiment". The term "another embodiment" should be understood as "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions may be included below. The definitions of the terms are consistent throughout the specification unless the context clearly dictates otherwise.

As has been briefly described above, the inventors have noted that in the existing single-vehicle detection, only the approximate position of the single vehicle can sometimes be obtained by GPS positioning, and the accurate position of the single vehicle cannot be effectively determined. This prevents the user or bicycle operator from being able to quickly find a bicycle after reaching the location of the GPS fix. Therefore, there is a need for an effective means to assist a user or operator in finding a target bicycle more conveniently when he or she arrives near the target bicycle.

The inventor also noted that, in the existing bicycle lock, a bluetooth signal transmitting device is generally provided, so that the user can move the end through a mobile phone to match with the bluetooth of the bicycle lock to achieve the unlocking purpose. However, because the bluetooth signal receiving device installed in the mobile terminal of the mobile phone of the user has low power, the bluetooth signal receiving device can only receive a very small range of bluetooth signals within several meters, and cannot detect bluetooth signals sent by a bicycle located at a long distance (for example, several tens of meters away) through the existing mobile terminal of the mobile phone.

Based on the above knowledge, the inventor proposes a detection device and a mobile device used in cooperation with the detection device, which can effectively utilize the short-range wireless signal sent by the lock of the bicycle to realize accurate positioning of the bicycle. Some example embodiments of the present disclosure will be described in detail below with reference to fig. 1 to 4. It should be noted that although the bluetooth signal is used as an example for illustration, it is not excluded that the short-range wireless communication mode of the existing or future other standards is used for communication in the bicycle. Thus, a detection device in this disclosure should be understood to be capable of detecting any short-range wireless communication signal that may be located.

FIG. 1 illustrates an application environment of a detection system according to an embodiment of the present disclosure. The bicycle 30 can broadcast, for example, a bluetooth signal over a range. The bluetooth signal is directly available to the mobile device 20 for bicycle identification and normal unlocking operations when the mobile device 20 is only a few meters away from the bicycle 30. However, when the mobile device 20 is distant from the bicycle 30 by a distance of several tens of meters, the built-in receiving antenna of the mobile device 20 itself will not be able to receive and recognize a weak bluetooth signal, as indicated by the dashed arrow in fig. 1.

Therefore, in the case where the above-described mobile device 20 is far from the bicycle 30, it is possible to achieve an extension of the detection range of the bluetooth signal, for example, to several tens of meters to several hundreds of meters, using the detection device 10 according to the present disclosure as a bluetooth power amplification peripheral. The probe device 10 receives the bluetooth signal from the bicycle 30 and processes it to obtain location information about the bicycle in the bluetooth signal, which is then transmitted to the mobile device 20. Based on this position information, the mobile device 20 can calculate the exact distance of the bicycle exactly, for example by means of corresponding devices and applications.

The detection device 10 according to the present disclosure may be, for example, a peripheral of the mobile device 20, and wirelessly communicate with the mobile device 20, or may be directly plugged into a charging port of the mobile device 20 as an accessory of the mobile device 20, so as to be integrated with the mobile device 20.

Fig. 2 shows a perspective view illustrating a detection device according to an embodiment of the present disclosure. Fig. 3 shows a block diagram of a detection device according to an embodiment of the present disclosure. The detection apparatus 10 according to the present disclosure includes a housing 130. In fig. 2, the housing 130 is rectangular. It should be understood that the housing 130 may be configured in any other geometric shape.

The housing 130 in fig. 2 has a first end face 131 at the front end. In this embodiment, the first end face 131 is designed for determining a probing direction of the probing apparatus 10 (as indicated by an arrow in fig. 2). The receiving device 100 is arranged at the first end face 131 in the housing 130 such that the receiving device 100 primarily receives bluetooth signals emitted from all the bicycles 30 from the direction in which the first end face 131 is directed. In this way, the direction of the bicycle 30 is determined by changing the pointing direction of the first end face 131 of the detection device 10 and by the intensity of the bluetooth signal from this direction.

In some embodiments, the bluetooth signal detection angle of the probe device 10 is configured to be 30 degrees. Through this kind of mode, can divide into reasonable angle range with all directions effectively, help improving the efficiency of looking for the bicycle.

The detection device 10 further comprises information extraction means 110. The information extraction device 110 is connected to the reception device 100, and processes the bluetooth signal received by the reception device 100. Identification information about the bicycle is usually included in the bluetooth signal, by means of which it can be determined, for example, whether the signal source of the bluetooth signal is from the bicycle and to which bicycle operator the bicycle as signal source belongs. From this, can filter noise signal effectively, improve the efficiency of looking for the bicycle.

For example, the single vehicle identification information may be information in the form of a mac address that uniquely corresponds to a single vehicle. By inquiring the mac address in the list, the bicycle number corresponding to the mac address can be determined. It should be understood that the bicycle identification information may also be any other information that uniquely identifies a bicycle.

The information extraction means 110 also extracts information about the signal strength from the received signal. The signal strength information depends on the distance between the bicycle 30, which is the source of the signal emission, and the probe device 10. For example, the signal strength information may be a signal strength value RSSI contained in the bluetooth signal, the absolute value of which decreases as the distance between the bicycle 30 and the probe device 10 increases. In this way, the distance between the bicycle 30 and the user of the detection apparatus 10 can be determined based on the signal strength information.

The probing apparatus 10 further comprises a transmitting means 120. The transmitting means 120 is connected to the information extracting means 110, and transmits the bicycle identification information and the signal strength information extracted by the information extracting means 110 to the mobile device 20 for subsequent processing.

In some embodiments, the transmitting device 120 may be configured to wirelessly transmit a signal containing bicycle identification information and signal strength information to the mobile device 20.

In some embodiments, the probe device 10 may also include an interface 160 for connecting with the mobile device 20. In this way, the detection device 10 can be connected with the mobile device 20 through the interface 160, so that a signal containing the bicycle identification information and the signal strength information is transmitted to the mobile device 20 through the interface 160 in a wired manner.

In some embodiments, the detection device 10 may be configured to be powered by the mobile device 20 via the interface 160. In this way, the detection device 10 and the mobile device 20 can share the battery built in the mobile device 20, so that a separate power supply for the detection device 10 is omitted, and the cost is saved.

In some embodiments, the detection apparatus 10 may also include its own power supply 140 for powering various devices in the detection apparatus 10. In this way, it is possible to make it unnecessary for the detection apparatus 10 to be connected to the moving apparatus 20, thereby making it easier to adjust the detection angle of the detection apparatus 10.

In some embodiments, the probe device 10 may further include a switch 150 located on the second end face 132 of the housing 130. The operating frequency of the detection device 10 can be artificially controlled by means of the switch 150. The detection device 10 is only operated, for example, when the switch 150 is continuously activated. Alternatively, the detection device 10 may be operated for a certain time, for example 30 seconds, after the switch 150 is triggered. In this way, power consumption of the detection device 10 can be effectively saved.

Fig. 4 shows a block diagram of a mobile device according to an embodiment of the present disclosure. The mobile device 20 may be, for example, a mobile terminal of a mobile phone, a mobile computer, a smart watch, or other electronic devices.

The mobile device 20 according to the present disclosure includes a receiver 200. The receiver 200 is configured to receive the transmitted bicycle identification information and signal strength information of the bicycle 30 from the probe device 10.

The mobile device 20 according to the present disclosure further includes a calculator 210. The calculator 210 is configured to determine a bicycle number of the bicycle 20 based on the bicycle identification information. For example, when the bicycle identification information is information in the form of a mac address, the calculator 210 may determine whether the information source of the signal is a bicycle by querying a preset lookup table, and further determine a bicycle number corresponding to the bicycle.

The calculator 210 is also configured to determine the distance of the bicycle 20 based on the signal strength information. For example, when the signal strength information is a signal strength value RSSI contained in a bluetooth signal, the distance of the bicycle can be determined by the following formula:

d＝10^((abs(RSSI)-A)/(10*n))

where d denotes the calculated distance, RSSI denotes the strength value (negative value) of the received signal, a denotes the signal strength value when the transmitting end (the bicycle 10) and the receiving end (the probe device 20) are spaced apart by 1 meter, and n denotes the environmental attenuation factor.

The mobile device 20 according to the present disclosure also includes a display 220. The display 220 is configured to display the determined bicycle number and the corresponding distance.

This is particularly advantageous when, for example, a problem with a particular numbered bicycle is indicated in the bicycle management system and needs to be recovered for repair, while the bicycle operator knows the approximate location of the bicycle only from the last GPS location signal sent by the bicycle. After the single vehicle operator arrives at the location corresponding to the GPS signal, the number and distance of the single vehicle located in each direction can be easily obtained by the probe device 10 and the mobile device 20 according to the present disclosure. By comparing the serial number of the fault bicycle with the obtained bicycle serial number, the position of the fault bicycle can be quickly found, and the fault bicycle can be immediately recovered and maintained. Therefore, the detection apparatus 10 and the mobile apparatus 20 according to the present disclosure can greatly reduce the operation cost of the shared bicycle, thereby bringing great convenience to the operation and maintenance of the shared bicycle.

It is to be understood that the above detailed embodiments of the disclosure are merely illustrative of or explaining the principles of the disclosure and are not limiting of the disclosure. Therefore, any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Also, it is intended that the following claims cover all such changes and modifications that fall within the scope and boundaries of the claims or the equivalents of the scope and boundaries.
